When the ancient Egyptians first started mining gold, management and security were fairly simple and primitive. Overseers watched every move workers made, and were selected partly because they spoke a different language, reducing the risk of collusion.

Today, management techniques have changed, and forbidding communication between workers and managers is impracticable. However, some of the same challenges still remain. Larger systems, and more people, can lead to more frequent errors, and a greater possibility of malfeasance.

The volume of precious metals has increased; tracking, valuing, and securing it has become even more critical.
